510S-14ISK Laptop - Very strange 'squares' on the screen

‎09-10-201703:26 PM

Hi - I hope someone can help to identify what the issue is here, please?

Bought a 510s-14 laptop back in June and and been using it fine until a few weeks back. When using the browser (Google Chrome), these 'squares' as can be seen from the photos below come up on the screen. I then have to shut the browser down and open it up again and it seems fine until it randomly happens again the same day or two days later. There is no pattern and I'm not doing anything in particular when it happens.

Run the Lenovo diagnostic tool, which found nothing and everything is upto date on the machine.

If not, you can open Chrome, and in the address bar type or paste: chrome://flags/ which will open a page with some of Chrome's experimental features, locate Accelerated 2D canvas(should be 3rd one down)and click the Disable button below it.
